When it comes to industrial power generation, few names carry the weight and reputation of Cummins. The Used Cummins DQGAB Diesel Generator represents decades of engineering excellence packed into a powerhouse that's built to run when you need it most. At Central States Diesel Generators, we're excited to have these proven performers in stock and ready to ship to your facility.

The DQGAB isn't just another generator – it's a testament to Cummins' commitment to delivering consistent, reliable power for the most demanding applications. Whether you're running a manufacturing facility, data center, hospital, or any critical operation that can't afford downtime, this generator has the specs and track record to keep your lights on and your business running.

The Cummins Advantage: Built to Last

Cummins has been synonymous with diesel engine reliability for nearly a century. When you see that red Cummins logo on a generator, you're looking at equipment that's been tested in some of the harshest environments on earth. From oil rigs in the North Sea to manufacturing plants in the desert, Cummins generators have proven time and again that they can handle whatever gets thrown at them.

The DQGAB model continues this tradition with robust construction and advanced engineering. This isn't equipment that'll leave you scrambling for repairs when you need power most – it's designed to run continuously, day after day, year after year.

Technical Specifications That Deliver

Let's dive into what makes the DQGAB such a reliable workhorse. This generator is rated at 1,500 kW standby power and 1,350 kW prime power – that's serious industrial-grade capacity that can handle substantial electrical loads without breaking a sweat.

At the heart of this machine is the Cummins QSK50-G4 NR2 engine, a cast iron V16 powerhouse that's turbocharged and low-temperature aftercooled. This engine configuration delivers:

  • Gross power output: 1,656 kW (2,220 HP) at standby rating
  • Bore and stroke: 159 mm (6.25 inches) both
  • Operating speed: 1,800 rpm
  • Compression ratio: 15:1
  • Lube oil capacity: 235 liters

The engine runs at 1,800 rpm, which is the sweet spot for balancing power output with long-term durability. Higher RPMs might give you more power, but they also mean more wear and tear. Cummins engineered this engine to provide maximum power while maintaining the reliability you need for continuous operation.

Fuel Efficiency That Makes Sense

One of the standout features of the DQGAB is its fuel efficiency. At full prime load, this generator consumes approximately 94.7 US gallons per hour. While that might sound like a lot, consider what you're getting – 1,350 kW of continuous prime power. That's incredibly efficient for this power class.

Even better, fuel consumption scales with load:

  • At 25% load: 33.1 gallons per hour
  • At 50% load: 53.6 gallons per hour
  • At 75% load: 74.2 gallons per hour

This means you're not wasting fuel when you don't need full power, but you've got it available when demand spikes. For facilities with variable power needs, this efficiency profile can translate into significant operational savings over time.

EPA Compliance Without Compromise

Environmental compliance is non-negotiable in today's industrial landscape. The DQGAB meets EPA NSPS Stationary Emergency Tier 2 emissions standards, so you can run this generator with confidence that you're meeting current environmental regulations.

This compliance doesn't come at the expense of performance, either. Cummins engineered this generator to deliver full power while maintaining clean emissions – the best of both worlds for modern industrial operations.

Why Used Generators Make Perfect Sense

Here's something many facility managers don't realize: a quality used diesel generator can be every bit as reliable as a new unit, especially when it's a Cummins with low operating hours. The units we have in stock typically show under 200 operating hours – that's barely broken in for an industrial diesel generator designed to run for decades.

Consider this: these generators are built to operate for tens of thousands of hours. A unit with 200 hours is essentially new equipment at a fraction of the new price. You get proven Cummins reliability, immediate availability, and significant cost savings all in one package.

When you factor in the lead times for new generators (which can stretch 12-18 months or more), used generators become even more attractive. Our used DQGAB units are inspected, tested, and ready to ship – no waiting, no delays, just reliable power when you need it.

Applications Where the DQGAB Excels

This generator's power rating and reliability make it ideal for a wide range of critical applications:

Manufacturing Facilities: Keep production lines running during utility outages or provide supplemental power during peak demand periods.

Data Centers: Ensure uninterrupted power for servers and cooling systems that can't tolerate even brief outages.

Healthcare Facilities: Power critical medical equipment and life support systems when grid power fails.

Commercial Buildings: Maintain elevators, lighting, and HVAC systems for tenant comfort and safety.

Industrial Processes: Support continuous manufacturing processes that can't be interrupted without significant cost or safety concerns.

The 1,350 kW prime rating means this generator can handle substantial electrical loads continuously, making it suitable for facilities with high power demands or multiple critical systems.
